PROBLEM TO BE SOLVED: To prevent a break of receiving data which is to be caused by disconnection of a transmission channel because an error during transmission is large. SOLUTION: Regeneration equipment is provided with a transmission part 5 for transmitting real data by radio, and an error inspection part 4 for inspecting the state of radio transmission channel of the transmission part 5 before video data, the real data, are transmitted. Correspondingly to the regeneration equipment, display equipment is provided with a transmission part for receiving the real data by radio, and an error inspection part for inspecting the state of the radio transmission channel of the transmission part before the real video data are received. The regeneration equipment transmits and receives data for inspection between the error inspection part of the regeneration equipment and the error inspection part of the display equipment, thereby deciding the state of the transmission channel.
